Reed Herb Overview
Phragmites australis, commonly known as common reed, is a plant with stems and rhizomes that have traditionally been used in medicine, particularly for digestive disorders. The stem and rhizome contain a variety of nutrients, including vitamin A, vitamin C, and several B-group vitamins. Additionally, they contain triterpenes such as beta-amyrin and taraxerol, as well as flavonoids like chrysoeriol, isoquercitrin, luteolin, rutin, and tricin. Besides its use for digestive disorders, common reed is believed to have diuretic effects and may stimulate sweating.
